Something is not correct in RMIR
Jp1 downloads just do not work for me. Work fine from IR.
I don't know why jp1.x serial is dragged into this error log since I'm downloading from 8910 using Tommy's cable for USB port and using the Delcom driver in WinUSB driver and what looks like correct pid and all that was in the RMIR window for linking the interface

I was going to try building jp1usb.dll version 0.03 under MinGW to see if that works any better, but I can't find the source. Anyone know where it is?

My apologies. It seems that I didn't upload the source. I've now done so, here.

My absence from these forums for the past few months has been the result of personal events, and is likely to continue. I still keep an occasional eye on things, however, and have just seen this thread and noticed my oversight._________________Graham

I've just done a JP1 download from my URC-8550 with the following setup: RMIR v2.01 Alpha 8, jp1usb v0.03, java version 1.6.0_23, WinUSB driver, interface set to JP1USB with auto-detect, and MS Vista. It worked without any problem. In case it is relevant, I haven't done any Windows updates for some weeks. So unless I misunderstand the problem, I am unable to reproduce it._________________Graham

Graham, great to see you stopped by
XP here and I, too, did auto-detect in one of many trials.

Makes me wonder if a Windows or Java update has broken it.

My java version is 6.0.24. I updated java 2/23/2011.
Last few Windows XP updates were 6/18/2010, 10/8/2010, 12/21/2010, 2/24/11 and 3/20/2011, in case any of it matters._________________Liz

Using the debugger and attaching to the Java process shows that the call to CreateFile (which opens the USB interface) fails with the error Access Denied. Using jp1usb.dll with a Windows test program does succeed-- at least past the call to CreateFile.

I haven't found a fix yet, but I suspect that the issue is increased security in Windows or Java. Can't let the computer get a virus from our remotes!
